Solvents
Follow manufacturers instructions.
Water-based Adhesives/Sealers
Those based on polymer emulsions and rubber
latexes may contain small amounts of volatile toxic
and harmful chemicals. Skin and eye contact
should be avoided and adequate ventilation
provided during use.
Hot Melt Adhesives
In the solid state, they are safe. In the molten state
they may cause burns and health hazards may
arise from the inhalation of toxic fumes.
Use appropriate protective clothing and a
thermostatically controlled heater with a thermal
cut-out and adequate extraction.
Resin-based Adhesives/Sealers, for
example Epoxide and Formaldehyde
Resin-based
Mixing should be carried out in well ventilated
areas, as harmful or toxic volatile chemicals may
be released.
Skin contact with uncured resins and hardeners
can result in irritation, dermatitis, and absorption
of toxic or harmful chemicals through the skin.
Splashes can damage the eyes.
Provide adequate ventilation and avoid skin and
eye contact.
Anaerobic, Cyanoacrylate (super-glues)
and other Acrylic Adhesives
Many are irritant, sensitizing or harmful to the skin
and respiratory tract. Some are eye irritants.
Skin and eye contact should be avoided and the
manufacturers instructions followed.
Cyanoacrylate adhesives (super-glues) MUST NOT
contact the skin or eyes. If skin or eye tissue is
bonded, cover with a clean moist pad and SEEK
IMMEDIATE MEDICAL ATTENTION. Do not
attempt to pull tissue apart. Use in well ventilated
areas as vapors can cause irritation to the nose
and eyes.For two-pack systems see Resin-based and
Isocyanate Adhesives/Sealers.
Isocyanate (Polyurethane)
Adhesives/Sealers
See also
Resin-based Adhesives.
Individuals suffering from asthma or respiratory
allergies should not work with or near these
materials as sensitivity reactions can occur.
Over exposure is irritating to the eyes and
respiratory system. Excessive concentrations may
produce effects on the nervous system including
drowsiness. In extreme cases, loss of
consciousness may result. Long term exposure to
vapor concentrations may result in adverse health
effects.
Prolonged contact with the skin may have a
defatting effect which may lead to skin irritation
and in some cases, dermatitis.
Splashes entering the eye will cause discomfort
and possible damage.
Any spraying should preferably be carried out in
exhaust ventilated booths, removing vapors and
spray droplets from the breathing zone.

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL

Noise Conditions
• Gear noise is typically a howling or whining dueto gear damage or incorrect bearing preload. It
can occur at various speeds and driving
conditions, or it can be continuous.
• Chuckle is a particular rattling noise that sounds like a stick against the spokes of a spinning
bicycle wheel. It occurs while decelerating from
64 km/h (40 mph) and can usually be heard all
the way to a stop. The frequency varies with
vehicle speed.
• Knock is very similar to chuckle, though it may be louder and occurs on acceleration or
deceleration. The teardown will disclose what
has to be corrected.
Clicking, popping or grinding noises may be caused
by the following:
• worn, damaged or incorrectly installed wheel bearing, suspension or brake component.
Check and rule out tires, exhaust and trim items
before disassembling the transmission to diagnose
and correct gear noise.
The noises described under Road Test usually
have specific causes that can be diagnosed by
observation as the unit is disassembled. The initial
clues are the type of noise heard on the road test
and driving conditions.
Vibration Conditions
Vibration at highway speeds may be caused by
the following:
• out-of-balance front or rear wheels.
• out-of-round tires.
Shudder or vibration during acceleration may be
caused by the following:
• damaged powertrain/drivetrain mounts.
• excessively high constant velocity (CV) joint operating angles caused by incorrect ride height.
Check ride height, verify correct spring rate and
check items under inoperative conditions.
Road Test
A gear-driven unit will produce a certain amount
of noise. Some noise is acceptable and may be
audible at certain speeds or under various driving
conditions, as on a newly paved asphalt road. The slight noise is in no way detrimental and must be
considered normal.
The road test and customer interview (if available)
provide information needed to identify the condition
and give direction to the correct starting point for
diagnosis.
1. Make notes throughout the diagnosis routine.
Make sure to write down even the smallest bit
of information, because it may turn out to be the
most important.
2. Do not touch anything until a road test and a thorough visual inspection of the vehicle have
been carried out. Leave the tire pressures and
vehicle load just where they were when the
condition was first observed. Adjusting tire
pressures, vehicle load or making other
adjustments may reduce the condition(s)
intensity to a point where it cannot be identified
clearly. It may also inject something new into
the system, preventing correct diagnosis.
3. Make a visual inspection as part of the preliminary diagnosis routine, writing down
anything that does not look right. Note tire
pressures, but do not adjust them yet. Note
leaking fluids, loose nuts and bolts, or bright
spots where components may be rubbing
against each other. Check the load space for
unusual loads.
4. Road test the vehicle and define the condition by reproducing it several times during the road
test.
5. Carry out the Road Test Quick Checks as soon as the condition is reproduced. This will identify
the correct diagnostic procedure. Carry out the
Road Test Quick Checks more than once to
verify they are providing a valid result.
Remember, the Road Test Quick Checks may
not tell where the concern is, but they will tell
where it is not.
Road Test Quick Checks
1. 24-80 km/h (15-50 mph): with light acceleration,a moaning noise is heard and possibly a
vibration felt in the front floor panel. It is usually
worse at a particular engine speed and at a
particular throttle setting during acceleration at
that speed. It may also produce a moaning
sound, depending on what component is
causing it. REFER to Tip-in Moan in the
Driveline Noise and Vibration Symptom Chart.
2. Acceleration/Deceleration: With slow acceleration and deceleration, a shake is

sometimes noticed in the steering wheel/column,
seats, front floor panel, front door trim panel or
front end sheet metal. It is a low frequency
vibration (around 9-15 cycles per second). It
may or may not be increased by applying the
brakes lightly. REFER to Idle
Boom/Shake/Vibration in the Driveline Noise
and Vibration Symptom Chart.
3. High Speed: A vibration is felt in the front floor panel or seats with no visible shake, but with
an accompanying sound or rumble, buzz, hum,
drone or booming noise. Coast with the clutch
pedal depressed (manual transmission) or shift
control selector lever in "N" (NEUTRAL)
(automatic transmission) and engine idling. If
vibration is still evident, it may be related to
wheels, tires, front brake discs, wheel hubs or
front wheel bearings. REFER to Shake and
Vibration While Driving in the Driveline Noise
and Vibration Symptom Chart.
4. Engine rpm Sensitive: A vibration is felt whenever the engine reaches a particular rpm.
It will disappear in neutral coasts. The vibration
can be duplicated by operating the engine at
the problem rpm while the vehicle is stationary.
It can be caused by any component, from the
accessory drive belt to the clutch or torque
converter which turns at engine speed when the
vehicle is stopped. REFER to Shake and
Vibration While Driving in the Driveline Noise
and Vibration Symptom Chart.
5. Noise and Vibration While Turning: Clicking, popping or grinding noises may be due to the
following:
• worn, damaged or incorrectly installed front wheel bearing.
• damaged powertrain/drivetrain mounts.
Road Conditions
An experienced technician will always establish a
route that will be used for all NVH diagnosis road
tests. The road selected should be reasonably
smooth, level and free of undulations (unless a
particular condition needs to be identified). A
smooth asphalt road that allows driving over a
range of speeds is best. Gravel or bumpy roads
are unsuitable because of the additional road noise
produced. Once the route is established and consistently used, the road noise variable is
eliminated from the test results.
NOTE:
Some concerns may be apparent only on
smooth asphalt roads.
If a customer complains of a noise or vibration on
a particular road and only on a particular road, the
source of the concern may be the road surface. If
possible, try to test the vehicle on the same type
of road.
Vehicle Preparation
Carry out a thorough visual inspection of the
vehicle before carrying out the road test. Note
anything which is unusual. Do not repair or adjust
any condition until the road test is carried out,
unless the vehicle is inoperative or the condition
could pose a hazard to the technician. After
verifying that the condition has been corrected,
make sure all components removed have been
installed.
Power Steering Conditions
Check for the noise in the following conditions to
verify the customer concern.
• Check for the noise in several temperature conditions.
• Is the noise from when the vehicle was new?
• Can the noise be repeated constantly or is it random?
• Check the condition of the vehicle age, mileage and service record.
• Interview the customer to find the operating condition in which the noise will occur. Test the
vehicle based on the detail(s) from the customer
interview.
• Follow the power steering operation noise condition tables below, to find which condition
the noise will occur.
Power Steering Operation Noise Check
Step 1: Check for NVH concerns from non-steering
components, which may sound like noises coming
from the steering system.
